Introduction EVM, or error vector magnitude, is essentially a scalar measurement of digital modulation accuracy, an important figure of merit for any source of digital modulation. This note shows how a vector signal analyzer helps optimize EVM performance of IQ modulators such as the LTC5598, a 5MHz to 1600MHz high linearity ...
